The old Meyer lemons I have seen are kind of round and look like they might be a cross between an orange and a lemon. I understand CA allows only the Improved Meyer but AZ still prohibits both. Our lemon tree is Lisbon, a vicious, thorny, prolific tree that needs to be cut back every few years. We get enough lemons from it for us, for several families of snowbird relatives, and still have quite a bit left over to haul to the food bank. People here tend to use he terms Ponderosa and Rough Lemon interchangeably but there is a difference. The fruit looks similar - large, seedy and bumpy.. But the Ponderosa is a smaller, thorny tree and is not a true lemon. Rough lemon is a larger lemon-sized tree and was used as a rootstock, primarily in the Zone 10 region around Yuma. It was pretty common 35 years ago when suckers were allowed to grow below the bud union but it is now pretty rare. ----- Original Message ----- From: "George Shirley" <gshirl@bellsouth.net> > Yeah, the CTV was the reason the Meyer Lemon was completely changed.
